[Bug 606238] Re: synaptic touchpad not recognized on dell latitude e6510 and others

[Florin9doi]

dturvene  alps_hw_init_v6_minimal works fine if alps_get_model is run
like in previous versions. For the new version, try this:

static int alps_hw_init_v6(struct psmouse *psmouse)
{
        struct ps2dev *ps2dev = &psmouse->ps2dev;
        unsigned char param[4];

        // previously sent by alps_get_model()
        // useless if alps_get_model() is run

        param[0] = 0;
        ps2_command(ps2dev, &param[0], PSMOUSE_CMD_SETRES);

        /* E7 report */
        ps2_command(ps2dev, NULL, PSMOUSE_CMD_SETSCALE21);
        ps2_command(ps2dev, NULL, PSMOUSE_CMD_SETSCALE21);
        ps2_command(ps2dev, NULL, PSMOUSE_CMD_SETSCALE21);
        ps2_command(ps2dev, NULL, PSMOUSE_CMD_GETINFO);

        /* Enter command mode */
        alps_enter_command_mode(psmouse, param);

        /* exit command mode */
        ps2_command(ps2dev, NULL, PSMOUSE_CMD_SETSTREAM);

        // end of alps_get_model duplicate

        // alps_hw_init_v6_minimal()
        ps2_command(ps2dev, NULL, PSMOUSE_CMD_SETSTREAM);

        param[0] = 0x64;
        ps2_command(ps2dev, &param[0], PSMOUSE_CMD_SETRATE);
        param[0] = 0x28;
        ps2_command(ps2dev, &param[0], PSMOUSE_CMD_SETRATE);

        return 0;
}
